Product Description

Fin Extruded Heat Sink Aluminum For Electronic Component Thermal

Precision-engineered aluminum heat sinks designed for optimal thermal management in electronic components and industrial applications.

Precision Extrusion Technology

Core construction utilizes precision extrusion molding with specialized custom molds and high-precision equipment
Manufactured from 6061/6063 high-purity aluminum alloy ingots as single-piece units
Eliminates need for splicing and welding, preventing thermal conduction faults and structural weaknesses
Precisely controls fin height, density, and thickness with uniform pitch error ≤ 0.1mm
Enables formation of dense teeth, wide surfaces, and irregular shapes for maximum heat dissipation area
Provides strong rigidity, excellent deformation resistance, and vibration resistance
Maintains stable heat dissipation performance without attenuation during long-term high-load operation

Manufacturing Efficiency

Extrusion process enables high-speed, large-scale continuous production
Increases production efficiency by more than 50% compared to welding and casting methods
